The Leinster scrum-half lasted less than a minute of his team's 19-13 loss to Wales at the Millennium Stadium on Saturday after being struck in the face by a clearance kick from Lee Byrne.

He suffered concussion and was replaced by Munster veteran Peter Stringer. Reddan is being monitored by Ireland's medical team in addition to seeing a neurologist this week as part of the injury management process.

He is yet to be ruled out of contention for the weekend, with coach Declan Kidney due to name his starting line-up on Wednesday.
